Sandvik Coromant Co.'s CoroDrill 870 is now available for both steel and cast iron drilling operations. The CoroDrill 870 is part of a new generation of exchangeable-tip drills and is designed to save time and reduce hole costs.
CoroDrill 870 can be tailored to optimize applications through diameter range, steps and length possibilities. Holes can be made more efficiently and closer to the specifications required, leaving them better suited to subsequent operations.
A highly secure interface between drill body and tip ensures reliability and precision, while the quick and easy tip change procedure helps to maximize active machining time. The new cutting edge geometries and grades provide a safe cutting process, allowing for increased penetration rates while maintaining chip control and increasing tool life.
The drill is available in diameter range: 12 to 25.90mm (0.472 to 1.020 inch) and lengths 3, 5 and 8 times drill diameter as standard. Each drill body has a unique interface size with matching tips to achieve hole tolerances of IT9 to IT10.
